Simpson Strong-Tie CI-LPL Long Pot Life Structural Injection Epoxy is a two-component, high-modulus, high-solids, moisture-tolerant epoxy specially designed for pressure injection, gravity feeding and flood coat filling of concrete cracks when substrate temperatures are between 60°F (16°C)–110°F (43°C).
Applications Pressure-injection of cracks in structural concrete Gravity-feed of cracks in horizontal concrete As a low-viscosity epoxy (2,000 cP) for repair of fine to medium width cracks 1/64"–1/4" (0.4–6 mm) in width For structural repairs For underwater pressure-injection applications
Meets the requirements of ASTM C881 & AASHTO M235, Type I/IV, Grade 1, Class C. Chemically bonds with the concrete to provide a structural repair. CI-LPL seals the crack from moisture, protecting rebar in the concrete from corrosion. Moisture-tolerant; can be used on dry and damp surfaces. Low surface tension at elevated temperatures allows the material to effectively penetrate narrow cracks. Formulated for maximum penetration under pressure. Suitable for pressure injection or gravity-feed applications. Non-shrink and resistant to oils, salts and mild chemicals. Can be used with metered pressure-injection equipment. Formulated for use in hot environments to 110°F. Freeze-thaw resistant.
